Figure 4
Simulations.
This figure shows the simulations reproducing the 4 different cases that we identified as France (FR), the Netherlands (NL), Finland (FI) and California (CA). In the FR case there is a main community, which is very well connected in the inside (γ ~ 1), with few links that reach out to external regions. The NL and FI cases are intermediate with well-structured external regions that still interact with the central one. In the last case, CA, there is a strong central region with many and progressively distant, small regions. The FI and CA cases present similar outreach indices due to the fact that, by definition, a huge mass of links in the immediately external regions is equivalent to having just a few interconnected nodes at great distance.
